Bellicist theories of comparative development predict increases in taxation as the result of military rivalries. Others claim that this causal relationship is contingent on particular geographical, institutional, and historical conditions. In this paper, we explore the conditional effects of military rivalries on taxation during the 19th and 20th centuries using time-series cross-section models. W

Sparse, non-negative signals occur in many applications. To recover such signals, estimation posed as non-negative least squares problems have proven to be fruitful. Efficient algorithms with high accuracy have been proposed, but many of them assume either perfect knowledge of the dictionary generating the signal, or attempts to explain deviations from this dictionary by attributing them to compon

In this work, we propose a time-recursive multi-pitch estimation algorithm, using a sparse reconstruction framework, assuming only a few pitches from a large set of candidates to be active at each time instant. The proposed algorithm utilizes a sparse recursive least squares formulation augmented by an adaptive penalty term specifically designed to enforce a pitch structure on the solution. When e

A growing political interest in the development of biorefineries is being shaped by climate change and a need to develop economically viable substitutes (i.e., fuels, products and chemicals) to those produced in traditional oil refineries. The pulp and paper industry in Sweden has been stagnating and it is therefore potentially promising to integrate biorefining into its activities as one way of d

Teachers have high occupational voice demands. The voice load of teachers is both environmental and individual. Little is known about the teachers' own view of the contribution from the environment and about the teachers' voice use at their work-place. Aim: The purpose was to investigate the voice use and prevalence of voice problems in teachers and to explore their ratings of vocally loading aspe

This authoritative Handbook examines the current state and the future needs of international law in addressing the key activities that pose threats to the marine environment. Its chapters explore the legal framework for protection of the marine environment, pollution of the marine environment, seabed activities and the marine environment, protection of marine biodiversity, regional approaches to t

We present compact modeling, DC and RF characterization of lateral and vertical nanowire MOSFETs. Lateral tri-gate nanowire devices on InP substrates have demonstrated a maximum gm=2.95 mS/ μm at VDS=0.5 V, and fT/fmax=290/350 GHz. Vertical gate-all-around InAs wires integrated on Si substrates have demonstrated gm=1.35 mS/μm and fT/fmax=100/155 GHz. We also demonstrate a non- parabolic, ballistic
